Math Functions

There is an extensive list of math functions available in Simul8 through the Formula Editor in Visual Logic. These can be used as a part of a command that requires a Logic Flow rule before the function. You will need to use square brackets around the Object/distribution/parameter. For example:

IF [ABS[gbl_variable]] >10

ABS

Returns the absolute value of a number, i.e. converts a negative number to a positive number.

For example, ABS[-3] returns 3.

ARCTAN

Returns Arc Tangent of the parameter.

COS

Returns Cosine of the parameter.

DAY

Converts number from time to day 1-7 calculated from the Clock Properties.

EXP

Returns e to the power of the parameter (natural anti-log).

HOUR

Converts number from time to hour 1-23.

INSET

Search through a series of numbers without the need to use multiple IF Statements.

Note

This Command is case sensitive and must be in capital letters.

For example, IF gbl_variable INSET[1-5,9,12] tests if the variable is equal to 1, 2, 3, 4, 5, 9, or 12.

LOG

Returns the natural logarithm of the parameter.

MINUTE

Converts number from time to minute 1-59.

NEG

Multiplies the number by -1.

RANDOM

Returns a random number between 1 and 0. The parameter entered must be zero.

REALMOD

Calculates the mod (remainder after divide) for real number, where \ is the mod operator.

For example, REALMOD[8\7.5] returns 0.5

ROUND

Rounds a number to the nearest integer. If the number to be rounded is exactly halfway between two whole numbers, the result is always the even number. This method of rounding is often called "Banker's Rounding". If you wish to always round to the lower integer value, use the TRUNC function.

SAMPLE

Gets a random value from a statistical distribution.

SHEETCOLN

Converts text sheet columns Label to numbers, for example, column A = 1.

SIN

Returns the Sine of the parameter.

SQRT

Returns the square root of the parameter.

TAN

Returns the tangent of the parameter.

TRUNC

Rounds number to integer by moving toward zero.

WEEK

Converts number from time to week number 1, week number 2 etc. Calculated using Clock Properties.
